[0002] Pig farming is an important industry in my country's agriculture. In large-scale pig farms, in order to ensure the breeding environment and prevent the breeding of a large number of bacteria, the farms need to be ventilated regularly.

[0003] When ventilating a pig farm, a ventilation device is used. Most existing ventilation devices consist of an outdoor fan embedded in the wall and connected to the ventilation duct in the pig farm. The fan transports outdoor air into the farm along the ventilation duct. In order to prevent some birds from flying into the ventilation device, a protective cover is installed on the outdoor fan duct.

[0004] In the existing ventilation devices, the protective cover of the outdoor fan is mostly fixed to the inside of the pipe by bolts. There are some disadvantages in the fixation. When the fan blades need to be cleaned, the workers need to remove multiple bolts on the protective cover and then remove the protective cover. The disassembly process is cumbersome and complicated, and the bolts are prone to stripping during frequent disassembly, resulting in the protective cover being unreliably fixed. For this reason, we propose a pig farming ventilation device to solve the problems existing in the existing ventilation devices. Utility Model Content

The angle between the two adjacent protrusions 9 and the line connecting the centers of the protective cover 3 is ninety degrees, and the shape of the connecting groove 10 is L-shaped. When the protrusion 9 is inserted into the interior of the connecting groove 10, it can rotate inside the connecting groove 10. When the protective cover 3 and the circular tube 2 are disassembled, the protective cover 3 is rotated so that the protrusion 9 on the inner wall of the protective cover 3 rotates inside the connecting groove 10 until the protective cover 3 cannot rotate. Then, the protective cover 3 is pulled outward to disengage the protrusion 9 from the interior of the connecting groove 10, and the protective cover 3 and the circular tube 2 can be disassembled, and the blades 5 inside the circular tube 2 can be cleaned. When installing the protective cover 3, the protrusion 9 is aligned with the connecting groove 10, and the protrusion 9 is inserted into the interior of the connecting groove 10, and the protective cover 3 is rotated until the protrusion 9 is rotated to the innermost end of the connecting groove 10, and the protrusion 9 is squeezed by the extrusion assembly to fix the protective cover 3.
